An evaluation of six methods used to measure 174 PPCP over two years is presented. The methods included direct inject and SPE with LC-MS/MS, GC/MS, or LC-FTMS. Most methods performed accurately and precisely during the course of the study. An additional 48 analytes did not meet performance criteria. Any differences in methods, detection limits, and performance issues were discussed.
